Mac;
You nailed it, it mutedd the cans. Not help there. I am experimenting with the harmonizer today, and sofar sounds like a remake of Alvin and the Chipmonks! I guess the sliders are sensitive.

So Robh;
I have a small mixer already, how do I hook it? Use line out from the computer into the mixer, and use the headphones out from the mixer for the vocals? I just have a lap top right now with MIC IN, and HEADFONES OUT. I lost my good studio in a recent divorce. Now making it all work from a laptop is a drag. However, the music I am getting now with BB/RT is far superior to what I had. Just the vocals are a problem. I used to have one of those Boss(?) harmonizers. It would follow you by just putting in the key, MIDI and all.
